It's heat resistant up to 425 degrees. They have cute little flippers that sit nicely over the edge of the cup, just like they are hanging on the edge of the shore dipping they tail in the water.
I love these. This set comes with 2 colors, pink and greenish gray. The greenish one looks close to the natural color and it's my favorite. The pink one is pretty too.These are really simple to use and they are such a whimsical fun way to have your tea. These make a great gift for your favorite tea lover or yourself. This is a two pack so you could keep one for yourself and give one to a friend. These are so much fun.You can find this on Amazon Here.
